To allwhom z'may concern:

Be it known that I,.J0HN H. GmMAN, a`

citizen of the United States, and a resident of Ottawa, in the count'yof La Salle and,V

State of Illinois, have Vinvented certain new and useful Improvements in Adjustable Supports for Cup Elevators, of which the following is va full, clear land exact specifica-l tion.

My invention is concerned with certain improvements upon elevators of the class shown in prior Patent No. 1,089,125, granted'March 3, 1914, to myself and Albert E. Gilman, in which a portion of a verticall conveyer-trough and the included conveyer chains and cups can be folded up out of the way to allow a wagon to be driven beneath it and into dumping position, the present application being a division of my application No. 877,646, filed December 17, 1914, for improvements in elevators. v

In the structure shown in the aforesaid patent, while means were shown for adjustably suspending the conveyer-troughl from the floor above the swinging section so that it could be raised or lowered to compensate for the sagging of the floors, yet vthe means there shown were unnecessarily Vcomplicated and not readily manipulated. In my presont invention, I have provided a simple and eflicient means that can be adjusted from the lower floor, which is that of the crib or barn driveway, fromwhich the adjusting vmeans is always accessible and easily manipulated.

'Io illustrate my invention, I annex hereto a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which,-

Figure 1 is a side elevation of a portion of an elevator having my improvements applied thereto, and showing the rear end of a wagon in dumping position; and

F1g. 2 is a detail in section on the line lines in Fig. 1, to the horizontal inoperative position, indicated in dotted lines, to permit a wagon to drive beneath the elevator and kvertical apertures 20a,

into the dumping position indicated. When the wagon has been driven into dumping position, thelower section 1201r the framework or trough is swung down from its dot- Vvted-line to its full-line position, the hopper Ylioor of the driveway. Y v

As the building settles afteran elevator has been installed, the beams 18 constituting the support for the second floor 19 are apt to sag, and consequently it is necessary to provide some Vsuitable means-for raising the elevator to keep it in the proper position relative to the Hoor of the driveway, and for this purpose I support the upper section 10and consequently the lower section 12,.from the bars 20, which are placed on the beams 18 on either side of the section 10. On these bars 20, I place the hook members 21, which have the horizontal top portions resting on the tops of the bars 20, and the lower horizontal portions 22 connected with the top portions by the web 23. Suitable studs 24 are supplied on either side of the section 10, preferably by extending a rod 25 through the section and through the tops Vof the upper straps 26 of the hinge for the twol sec'- tions. The hinge straps 26 are securely bolted to the bottom of the upper section 10, and the hinge straps 26a Vare similarly securely bolted to the top ofthe lower or swinging trough-section 12, Vand the-pivot for the'hinges on either side is preferably formed by a rod l1 passing through the overlapping portions of thehinge straps 26 and 26a. I ,place on the studs24 the eyes of the eye-bolts 27, which have their threaded upper ends extended through suitable apertures in the lower horizontal portions 22 of the hook members 21, so that by adjusting the nuts 28 onthe ends of the eye-bolts 27 the elevator frame can be raisedasmuch as may be necessary to take care of the sagging of the beams 18. ward adjustment of the threaded ends of the eye-bolts 27 I bore through the beams, 20, the

To accommodate the upindicated in dotted it will have its outer end extend beneath the lines in both figures, into which apertures the upper ends of the eye-bolts 27 extend if it is necessary for them to be raised that much.

joists, hook members having their uppermost horizontal flange resting on the beams, studs projecting from the sides of the framework, eye-bolts having their eyes over the studs and having their threaded ends extending upward through the lowerhorizontal flanges of the hook members, and nuts coperating with the bolts and hook members to regulate the height of the framework.

2. In an elevator, the combination with the joists of a building, of a vertical framework depending through and between the joists, a swinging frame portion hinged to the stationary portion below the joists,

Copies of this patent may be obtained for ve cents each, by addressing the hinges comprising hinge straps secured to the bottom of the stationary frame section and to the top of the swinging section, a hinge rod passing through the overlapping ends of the hinge straps, a suspension rod passed through the stationary frame section and the upper ends of the upper hinge straps, supporting beams resting on the joists, hook members having their uppermost horizontal flanges resting on the beams, eye-bolts having their eyes over the outer ends of the suspension rod and having their threaded ends extending upward through the lower horizontal flanges of the hook members, and nuts cooperating with the bolts and hook members to regulate the f height of the framework. Y

In witness whereof,'I have hereunto set my hand and affixed my seal, this 4th day of June A. D. 191.5.
